Red Shift Cams® 576 for Twin Cam® Engines

The Red Shift Cams® RS576 was developed off of the success of the RS575 cam, but meant to work with the heavier springs and valves that are present in CVO motorcycles and many aftermarket engine builds.

The new profile yields a quiet valve train when used with heavier 5/16" stem valves and higher performance valve springs. This is an excellent cam to use in CVO engines, and really shines with more compression and increased airflow are added.
